West Highland Flora

ID: Leafy part of frond triangular in shape, and held
horizontally on a vertical stalk. Lower basal pinnule on lowest pinna
about equal in size to third pinna from base. (Neither of these
characters visible in pic on left owing to cramped conditions of plant,
but are shown well in pic below)

Other features: Sori small and near the margins.
Stalks blackish. Frond rolled into 3 balls when young. Not
tufted, fronds arise singly.
